I was doing some research for the 2011 new boats and it looks like that the Indmar MCX is now rated at 230 kW which equals 308 hp what gives, they detuned it that much so that the Ilmor will be more appealing at 239 kW=320 hp. Also looking on dealer websites they all still rate the MCX at 350 hp, what gives? who is accurate? also the L96 is rated at 284 kW = 380 hp. Indmar has no hp or kW ratings this is from MC's site. My math might be off but 1kilowatt=1.36horsepower.
